Mobile Fidelity Electronics SourcePoint V10 Master Edition Floorstanding Speakers at Vinyl Sound Toronto Canada

The SourcePoint V10 Master Edition is a flagship 3-way floorstanding loudspeaker from Mobile Fidelity Electronics (Mofi Electronics, USA), available at Vinyl Sound in Toronto, Canada. Designed by internationally acclaimed audio engineer Andrew Jones — whose credits span KEF, Pioneer, TAD, and ELAC — this tower represents a ground-up evolution of the celebrated SourcePoint platform. Each cabinet deploys ten 10-inch drivers, including a concentric midrange/tweeter, twin woofers, and dual rear-firing passive radiators, delivering bass extension down to 27 Hz and a sensitivity of 91 dB. The V10 Master Edition has earned praise from Hi-Fi News (Outstanding Product) and Audiograde (Editor's Pick), cementing its place among the most accomplished floorstanders available today.

Concentric Driver Architecture and Passive Radiator System

At the core of each SourcePoint V10 Master Edition cabinet sits Andrew Jones's Twin-Drive concentric assembly: a 10-inch paper-cone midrange with a 1.25-inch soft-dome tweeter mounted concentrically in its throat. Because both drivers share a single acoustic center, they radiate sound from an identical point in space, eliminating the time-arrival errors that plague conventional two-driver baffles and producing a wide, precisely focused soundstage. To handle deep bass without compromising the concentric unit, Jones added twin 10-inch paper-cone woofers per cabinet, each engineered with dual-opposed neodymium magnets, a short-coil/long-gap underhung motor, and a ribbed roll surround for enhanced linearity. Two 10-inch rear-firing passive radiators — mounted in isolated internal chambers — reinforce low frequencies down to 27 Hz, moving the same air as a large bass port but without the turbulence or port noise that plagues conventional vented designs at high volumes. The result is bass that feels authoritative and articulate even during demanding passages.

Master Edition Tunable Crossover Network

The V10 Master Edition crossover is hand-built with audiophile-grade polypropylene film capacitors, metalized-film resistors, and air-core inductors on separate circuit boards dedicated to the bass, midrange, and high-frequency bands. This triple-board architecture eliminates inter-band interference within the crossover itself, lowering distortion across the entire audible range. A rear-mounted three-position rocker switch lets you dial in treble output — low, mid, or high — with approximately 1 dB of adjustment per step, allowing the V10 Master Edition to integrate precisely with a wide range of room acoustics and personal listening preferences. Crossover points are set at 130 Hz and 1.4 kHz, handing off smoothly between the passive radiator/woofer section, the 10-inch midrange, and the soft-dome tweeter.

Multi-Faceted Baffle and Cabinet Construction

The SourcePoint V10 Master Edition stands 48.8 inches tall in a resonance-free, multi-chambered cabinet constructed from thick MDF with extensive internal bracing. Its sculpted multi-faceted baffle uses strategically angled planes around each driver to scatter edge diffraction and eliminate the comb-filtering reflections that smear imaging on flat-fronted enclosures. Each woofer and passive radiator occupies an isolated internal chamber, preventing bass energy from contaminating the midrange cavity. Magnetic fabric-wrapped grilles clip on quickly for casual listening while preserving the baffle's distinctive contoured profile. Cabinets are finished in genuine book-matched Walnut or Black Ash real-wood veneer, sealed under a durable satin clear coat that protects the natural grain while giving each pair a uniquely matched appearance.

• Twin 10-Inch Woofers with Underhung Motors: Dual-opposed neodymium magnets and a short-coil/long-gap design minimize distortion and preserve clarity during high-excursion bass passages.
• Dual Rear-Firing Passive Radiators: Two 10-inch passive radiators extend bass response to 27 Hz with the air-moving capacity of a large port and the low-turbulence character of a sealed enclosure.
• User-Tunable Treble Control: A rear-mounted three-position switch adjusts high-frequency output by approximately 1 dB per step, adapting the V10 Master Edition to different rooms and amplifier pairings.
• Audiophile Master Edition Crossover: Polypropylene film capacitors, metalized-film resistors, and air-core inductors on separate bass/mid/HF boards deliver ultra-low distortion and precise phase alignment at each crossover point.
• Multi-Faceted Sculpted Baffle: Angled planes around each driver minimize edge diffraction and unwanted reflections, producing razor-sharp imaging and a wide, even dispersion pattern.
• Resonance-Free Multi-Chambered Cabinet: Isolated internal chambers for each driver section, thick MDF walls, and extensive internal bracing eliminate cabinet colorations that obscure fine musical detail.
• Magnetic Fabric Grilles: Tool-free magnetic attachment makes grille removal quick and easy; the form-fitting profile preserves the baffle's distinctive shape when grilles are in place.
• Book-Matched Real-Wood Veneers: Genuine Walnut or Black Ash veneer panels are book-matched for seamless grain flow and sealed under a hard-wearing satin clear coat.
• 91 dB Sensitivity: High sensitivity and a benign 6-ohm nominal impedance make the V10 Master Edition compatible with a wide range of amplifiers, from 30-watt tube amplifiers to powerful solid-state designs.

Frequently Asked Questions

What is the MoFi Electronics SourcePoint V10 Master Edition?

The SourcePoint V10 Master Edition is a flagship 3-way floorstanding loudspeaker from Mobile Fidelity Electronics (USA), built around ten 10-inch drivers per pair — including a concentric midrange/tweeter, twin woofers, and dual rear-firing passive radiators per cabinet. It extends bass to 27 Hz, reaches a sensitivity of 91 dB, and handles up to 200 watts. Designed by Andrew Jones and refined with a hand-built Master Edition crossover, it is the most ambitious speaker in the MoFi Electronics SourcePoint lineup.

How does the SourcePoint V10 Master Edition compare to the Klipsch Forte IV and the KEF R11 Meta?

The SourcePoint V10 Master Edition occupies a distinct technical position relative to both competitors. Against the Klipsch Forte IV, the V10 matches horn-loaded efficiency with a high 91 dB sensitivity while delivering deeper low-frequency extension to 27 Hz versus the Forte IV's 34 Hz, and replaces the Forte's bass-reflex port with passive radiators for lower turbulence at high volumes. Compared to the KEF R11 Meta, which uses KEF's Uni-Q coaxial driver in a conventional two-way bass arrangement, the V10 Master Edition goes further with a full three-way architecture, ten total 10-inch drivers, and Andrew Jones's own evolution of the concentric driver concept he helped develop during his tenure at KEF. Both the Forte IV and R11 Meta are accomplished speakers, but neither pairs passive radiator bass technology with a large-format concentric midrange/tweeter in a single tunable cabinet.

Can the SourcePoint V10 Master Edition be driven by a tube amplifier?

Yes, the SourcePoint V10 Master Edition works well with tube amplifiers rated at 30 watts or more. Its 91 dB sensitivity means it reaches high listening levels from modest power output, and its nominal 6-ohm impedance with a 4.5-ohm minimum presents a manageable load for well-designed tube amplifiers with 4-ohm or 8-ohm taps. The tunable treble switch allows further matching to the tonal character of the amplifier in use.

What is a concentric driver and why does MoFi Electronics use one?

A concentric driver is a loudspeaker unit in which the tweeter is mounted at the acoustic center of the midrange cone, so both drivers radiate sound from precisely the same point in space. MoFi Electronics uses this approach in the SourcePoint V10 Master Edition because it eliminates the time-arrival errors and lobing artifacts that arise when a separate tweeter and midrange are offset from each other on a flat baffle. The result is a wider, more stable sweet spot, more consistent off-axis response, and more lifelike imaging than a conventional two-driver arrangement can achieve at the same crossover frequency.

What does the tunable crossover do on the V10 Master Edition?

The Master Edition crossover includes a rear-mounted three-position rocker switch that adjusts treble output by approximately 1 dB per step — low, mid, or high. This allows the SourcePoint V10 Master Edition to integrate properly into rooms with different acoustic treatments, and to match the tonal character of a wide range of amplifiers and source components. The crossover itself is built with polypropylene film capacitors, metalized-film resistors, and air-core inductors on separate bass, midrange, and high-frequency circuit boards for ultra-low distortion.

Where can I buy the MoFi Electronics SourcePoint V10 Master Edition in Toronto or Canada?

The MoFi Electronics SourcePoint V10 Master Edition is available at Vinyl Sound, an authorized Mobile Fidelity Electronics dealer located in Toronto, Canada. Vinyl Sound carries the full MoFi Electronics speaker lineup and can arrange a listening demonstration for prospective buyers in the Toronto area.

What room size suits the SourcePoint V10 Master Edition?

The SourcePoint V10 Master Edition is designed for medium to large listening rooms where its bass extension to 27 Hz and wide dispersion can fully develop. At 48.8 inches tall and weighing 160 lbs per cabinet, each speaker requires adequate floor space and benefits from placement at least 2 to 3 feet from rear and side walls to allow the rear-firing passive radiators to breathe. The tunable treble control and 91 dB sensitivity give the V10 Master Edition a degree of acoustic flexibility that makes it usable in rooms that might otherwise overload with a similarly sized ported design.

How does the passive radiator system in the V10 Master Edition differ from a bass-reflex port?

The dual 10-inch rear-firing passive radiators in the SourcePoint V10 Master Edition move bass air through the cabinet wall using a mechanically tuned diaphragm rather than an open tube or slot. This approach produces the same low-frequency extension as a large bass-reflex port but avoids the port turbulence, chuffing, and group-delay artifacts that ported enclosures can exhibit at high listening levels. Each passive radiator is housed in its own isolated chamber, preventing bass energy from interfering with the woofers or midrange cavity and maintaining clarity throughout the frequency range.
